This series of projects explore concepts of radio communications. We use LEDs to generate (very high frequency) radio waves and photo-resistors to take the place of radio antennas. These ideas are ...

ARD1 (Transmitter): Reads button inputs. Sends a signal via Serial Tx to ARD2 when buttons are pressed. Reads button inputs. Sends a signal via Serial Tx to ARD2 when buttons are pressed. ARD2 ...

🧠 Working Principle A potentiometer acts as the Synchro Transmitter, generating an analog voltage representing angle. Arduino reads this analog input. The value is mapped and sent to control a servo ...
